The present invention provides a hydroprocessing catalyst for hydrocarbon oil having high desulfurization activity, high wear strength and pressure strength, and a method for producing the same. The hydrotreating catalyst uses an alumina-phosphorus carrier, and the carrier contains phosphorus in an amount of 0.5 to 2.0% by mass on the oxide basis, and each metal of Group 6A and Group 8 of the Periodic Table. Is supported on the carrier, the specific surface area is 150 m 2 / g or more, the total pore volume measured by mercury intrusion method is 0.40 to 0.75 ml / g, and the log differential fineness measured by mercury intrusion method is used. In the pore volume distribution, there are two maximum peaks between the pore diameters of 6 nm and 13 nm, the wear strength is 0.5% or less, and the pressure resistance is 15 N / mm or more. The carrier is produced, for example, from a hydrate obtained by adding phosphorus to an alumina hydrate obtained by using two kinds of mixed solutions obtained by mixing an aqueous solution of an acidic aluminum salt and an aqueous solution of a basic aluminum salt.
